Methods and systems for automatically tracking the rerouting of logical circuit data in a data network

Abstract

An example method involves generating, without manual intervention, a table to store current reroute statistics based on rerouting of data from a logical circuit that has failed to a logical failover circuit in a network. The current reroute statistics include trap data corresponding to the logical circuit. The trap data includes a committed burst size. The logical circuit is identified by a first logical circuit identifier. The logical failover circuit is identified by a second logical circuit identifier. The first and second logical circuit identifiers are renamed until the logical circuit has been restored from failure. The table is updated, without manual intervention, to store updated reroute statistics. The updated reroute statistics include updated trap data corresponding to the logical circuit. The updated reroute statistics are based on a change in status of the logical circuit corresponding to a dropped frame when the committed burst size has been exceeded.
